Cant click on scrollview element

Hello All,

I am new to Appium!

I am not able to click on a element within scroll view which is out of android viewport.

I have used below code but still i’m failling:
MobileElement makeTextLocator = (MobileElement)
driver.findElementByAndroidUIAutomator(“new UISelector().className(“android.widget.ScrollView”).index(0).childSelector(new UiSelector().className(“android.widget.LinearLayout”).index(13))”);

Please help me!

Thank you,
